I'm not sure the new Nacra SL16 would be compettitive if raced in the F16 class. From what I have read, it has a bit less sail area, is a bit heavier, and has no daggerboards, so I doubt if it will point as well going upwind. Still, it might measure in to the F16 box rule, which specifies maximum sail area, minimum weights, not vice versa.

The SL 16 was supposed to be the new US Sailing youth cat so if you have kids and want them to get into a youth sailing cat, that would be the one. But it's not really an F16 per se. I wish they had built it more to the F16 rule, it would have been a better boat.
